BrakesOperation of Brakes
Section § 26450
This law requires all motor vehicles to have a service brake system, and all vehicles except motorcycles must also have a parking brake system. These two systems must work separately from each other.
If they are connected, they must be designed so that a failure in most parts doesn't leave the vehicle without operable brakes, except if the failure is in parts like brake drums or shoes.
Section § 26451
This law requires every vehicle's parking brake system to be able to keep the vehicle stationary, regardless of how it's loaded, on any grade or incline, as long as the surface is not icy, snowy, or covered in loose debris. The brake must be strong enough to lock the wheels to the limit of traction.
The parking brake can be operated manually by the driver, through spring action, or using a separate energy source dedicated to the parking brake. Once engaged, the parking brake must stay in place using only mechanical means.
Section § 26452
This law requires that all motor vehicles have brakes that can stop the vehicle even if the engine stops working. The brakes must be capable of bringing the car to a halt within the legally required stopping distance.
Section § 26453
This law requires that car brakes and their parts are kept in good shape and work properly. Brakes should be adjusted to work as evenly as possible on both sides of the vehicle.
Section § 26454
This section specifies the braking requirements for different types of vehicles under various loading conditions. It states that service brakes must be effective enough to stop and hold the vehicle. Each vehicle type, whether passenger-carrying or property-carrying, has specific stopping distances and braking force requirements. The stopping distance for service brakes is defined for speeds of 20 miles per hour, and emergency brakes must also meet specific stopping distances without the help of other brakes. Furthermore, deceleration rates are provided for vehicles to ensure they can stop safely. Testing conditions for these requirements include a flat, dry, and smooth surface.

Section § 26455
This law explains how to determine the weight classification for stopping distance requirements of certain motor vehicles used to carry goods, which lack a manufacturer's weight rating plate. If a vehicle has less than six wheels, it counts as weighing less than 10,000 pounds. If it has six or more wheels, it counts as weighing 10,000 pounds or more.
Section § 26456
This section specifies the conditions under which stopping distance tests for vehicles should be conducted. The tests must be performed on flat, dry, and smooth surfaces without loose debris and should start from a speed of about 20 miles per hour. Additionally, such tests should not be done at speeds greater than 25 miles per hour on a highway.
Section § 26457
This law states that certain types of vehicles, like special mobile equipment, logging vehicles, vehicles with a special permit, or those without a body or load, don't have to meet standard stopping distance rules. However, if any of these vehicles can't stop within 32 feet from a speed of 15 mph, they must not be driven faster than a speed that would allow them to stop within 32 feet.
Section § 26458
If you're towing a vehicle, the brake system should be organized so that the towing vehicle's brakes control all the service brakes on both vehicles. This applies if the towing vehicle or the towed vehicle has power brakes.
However, it's okay to have an extra control to operate just the brakes on the trailer. This rule doesn't apply to certain vehicle combinations, like those in towing operations or disabled vehicles being towed, as long as they meet specific stopping distance requirements. There are also exceptions for trailers with special brakes that can activate if they detach and hold for 15 minutes.
Section § 26458.5
This law states that if your vehicle has a separate brake control for a trailer, you can't use it instead of your main vehicle brakes unless the main brake system fails.
